Specification of Letters Patent.

Patented Dec. 13, 1921.

` Application filed January 28, 1921. Serial No. 440,739.

To all whom t may conce/fa:

Be it known that l, HARRY S. Toonen, a citizen of the United States, and a resident of Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful improvements in Pumps, of which the following is a specification.

rlhis invention relates to pumps and the operating means therefor.

An important object of this invention is to provide a pump having novel means whereby the same may be operated at a point remote from the same so that a pump operating apparatus in the form of a steam engine or the like need not be installed with the pump.

The invention forming the subject matter of this application aims also to provide a pump having fluid pressure columns provided with novel means whereby the excess fluid within the column is discharged and whereby the necessary quantity of fluid is maintained in the column so that there will he no lost motionl in the operation of the pump.

-i-i further object of the invention is to provide arpump which may be operated o n the surface of the water or submerged and which may be arranged ina variety of vpositions or which may be suspended in midair as when hanging in the shaft of a mine.

A further object of lthe invention is to provide a pump having its working or moving parts inclosed so as to be protected from damage due to the flying of pieces of rock and so forth as a result cf blasting in the mine.

A still furtherA object is to provide a pump ofthe class described which is light and which therefore may be conveniently transferred from place toplace as the occasion requires.

A further object of the invention is to provide a pump which by reason of the absence of vibration need not be chained or anchored to a base.

The invention forming the subject mattei' of the application aims further to provide a pump of the class described which is reliable, efficient, and cheap to install. Y

In the accompanying drawings, forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is an elevation of a power transmitting mechanism, `parts being shown in section.

Fig. 2 is a sectional view through a check valve'embodied in the invention.

F ig. 3 is a fragmentary elevation of the pump, parts being shown in section.

In the drawings, wherein for the purpose of illustration is shown the preferred v embodiment of the invention, the numerals 6 and 8 designate a pair of conduits or co1- umns through which a quantity offluid is adapted to pass back and forth under pressure for operating a pump to be later described. As illustrated in Fig. 1 the upper portions of the conduits 6 and 8 have connection with elbows 9 and 10 which are in turn connected to nipples 11 by means of the usual flanges 12. The nipples 11 have connection with the T-coupling 14. The couplings 14 have connection with a pair of alined cylinders 15 within which pistons 1'6 reciprocate for the purpose of moving the liquid within the columns 6 and 8 back and forth whereby to operate the aforesaid pump. The pistons may be of any desired typeand are connected by a piston rod 18 having its intermediate portion formed with a pair of shoulders or flanges 2O between which an operating device 22 is arranged.

The operating device 22 may be the power transmitting member of a steamor other engine and is operated to reciprocate. the piston rods 18 whereby the pistons 16 are reciprocated within the cylinders 15. rlhe power transmitting mechanism which includes the cylinders 15, the pistons 16 and associated elements is of course constructed separately from the power plant to which the arm 2Q is connected and in fact the power transmitting mechanism is in the nature of an attachment for the power generator.

In the operation of the improved pump, the columns 6 and 8 must be completely full so that there will be no lost motion or lack of efficiency in the operation of the pistons 16.

To provide the means whereby the columns 6 and 8 will at all times be adequately supplied with fluid, l have connected a relief conduit 26 to each of the Ts 14. As illustrated in Fig. 1, the upper end of each conduit 26 is connected to a T 27 which is in turn connected to a fluid supply pipe 29 by means of a connecting pipe 30 in which is interposed a check valve 32. With reference to Fig. 2

it will be observed that the check valve 32 has a flap 84 which is swung to its openV position when pressure of; the fluid Vin the reservoir 36 rises above the pressure of the fluid in the coliunn 6. However7 the shoulder 88 formed within the casing ot' the check valve prevents the flap 34 from permitting the passage oiC liquid from the columns to the reservoir. ln this manner the columns 6 and 8 are at all times provided with an ade uate supply of water orother fluid.

owever, should the pressure of the fluid be greater than is required to operate. the pump the pressure will back up through the relief conduit and thus open a valve 40,

which is connected to the pipe 30. As illus-V trated in Fig'. l, thevalve 40 is provided with a seat normally engaged by valve head A coiled 42which acts to close the valve. spring 44 surrounds the stein or the valve head and serves to normally seat the valve head so that no fluid is permitted to passV through the valve. The tension of the spring 4V44 may be adjusted by a nut 46 threaded in the rear end` of the casing. it will `be' observed also that the adjusting nut. 46 terms a guide for the stem ot the valve head. Whenthe pressure of the Huid becomes greater than is necessary to operate the pump and when the pressure exceeds the pressure of the spring 44, the valve head 42 will be unseated and will pass up through the adjacent overllow pipe 48 and into the reservoir or storage tank 86.

In preparing the transfer mem'ben for operation air relief valves-49 connected to the T members27 are opened so that any air contained within the conduits will pass ott through the air relief valve 49.

Ybe varied in size.

pistons 58 and 60 and the cylinders 56. 5l

rlhe improved pump includes an intermediate cylinder 50with which outer cylinders 5l and 52 are alined. Y is illustrated in F ig. 8, a coupling` 54 is connected to each of the ends o' the cylinder 50 by means of flanges 55 and is connected to the inner ends ot the cylinders 5l and 52 by means of flanges 56. rl"he cylinders 5l and 52 are connected to the lower portion ot the column or conduits 6 and 8 so that fluid presure within the columns 6 and 8 will act on the pistons 58 within the cylinders 5l and 52.

A piston rod 59 is connected to cach piston 58 and liasits adjacent ends connected to the main piston 60 slidable within the intermediate cylinder 50. The outer cylinders 5l`and 52 are less in diameter than the intermediate cylinder 50 and therefore when the pistons 58 andv 60 reciprocate together the'chambers termed between the same will lt will be seen that 'the and 52 provide two chambers between/the pistons.

' The vpistons 58 are each moved inwardly or toward the cylinder 50 since the pistons of liquid will be drawn into the opposite The subsequent inward inove ment of the piston 58 discharges'the liquid:

chamber.

i' 58 are operated solely by the pressure o within the other chamberinto the discharge j branch of a discharge conduit or Y66 which may extend to any suitable point of discharge. A. one-.way valve 68 is ranged within the coupling 64 and serves to limit the movement .of the liquid within the branches 62 to one direction. lThat is the valves 68 are one way valves yand do not permit of the discharge of the water. VCoiled springs 70 are employed for normally seatingjthe valves on the ends 7 2 of the branches. n Y

ach coupling 65 is provided with an outlet valve"72 which seats on thD end 'T8 oit the coupling and normally closes the l opening in the same. However,V when the pistony 58 moves inwardly, the liquid confined within the'chamber is passedthrough the openings in the'coupling andelevates the valve 72 so that the fluid may passen through the branch -65 and out through th discharge member 66. Y @ne outlet valve 72"V is of course provided for each and as the water is passed more vto the branches` 65,the outletor discharge valve 72 will work opposite to each other. A coiled spring "74 confined between the head of the valve and a cross rod V75 is employed for normally seatl ingthe valve. l/Vhen `the piston 58 moves outwardly, the valve V72, 1s of course'closedy and the water'within the discharge column Y 62 will not be chamber.

In the use of the improved apparatus, the columns 6 and 8 are connected to the cylinders 5l and'52 so that the reciprocation of the pistons will result in moving the fluid contained within the columns 6 and 8 back and forth. This baclrl and forth movement thus imparted to the iluid within the colpermitted to enter the iio umns 6 and 8 results in the reciprocatioir of thespistons 58 so that the fluid will be sucked up through thel suction member 68 into the chambersiormed betweentons 58 and 60. l/Vhen one piston 58 is suck` ing water into one ot the chambers the'other piston 58 is discharging the waterfi-nto one ot the discharge branches 55.

the pis# ln starting the improved pump .itcone of c the columns is filled with itluid andthe piston for that column advances. a streng pres-Y v sure will be created which will result in opening of. one of the valves 40 so that the excess liuid will overlow into the reservoir 36.V Thistakes place,A howeverj'only in case the piston 58 operated by the fluid in that column is already in its advanced position. The longitudinal movement of the othei' piston draws a quantity of fluid from the reservoir through the associated check valve 252 so that a quantity of liquid is supplied to the other column. ln this manner adequate and even supply of fluid is maintained in the columns 6 and 8.

The pump illust ated in Fig. 3 may be lowered into the shaft of the mine or other place for the purpose of draining the water from the same. rThe pump operates without being chained or otherwise anchored and without the necessity of providing a seat or mounting for the same. This is accounted for by the lack of vibration. The outward movement of the piston 16 is yieldably limited by a pair of coiled springs 8O which are arranged at the ends of the cylinder.

As previously stated the pump is located at a point remote from its source of power so that the pump need not be inspected frequently. ln fact all parts of the pump are inclosed so that the same are not visible.

By inclosing the working parts of the pump, the same are protected from flying stone and the like as a result of blasting mines.

A number of the improved pumps may be operated from a central power unit, so that power plants may remain stationary while the pumps maybe moved from place to place as the occasion requires.
